Periumbilic rebound abdominal tenderness

This code signifies the presence of pain experienced upon the release of pressure from the periumbilical region of the abdomen, indicating peritoneal irritation. It is a specific physical exam finding suggestive of an underlying inflammatory process within the abdomen.

Assign this code when documentation explicitly states "periumbilical rebound tenderness" during a physical examination. This finding is often associated with conditions like appendicitis, diverticulitis, or other causes of localized peritonitis.

• Differentiate from generalized or other specified abdominal rebound tenderness (R10.820, R10.829).
• Requires clear documentation of both the location (periumbilical) and the specific finding (rebound tenderness).
• Always code the underlying definitive diagnosis if established, with this code serving as a supporting symptom.
